Stream Decoding with Confidence Scores at Room and Cryogenic Temperatures
Maries Tahaab, Tim Chan, James Kirkman +1
In fault-tolerant quantum computing, fast and accurate decoding is crucial. Snowflake is a decoder for the surface code that runs in a streaming fashion. In this paper, we implemen…

Error mitigation for logical circuits using decoder confidence
Maria DincÄ, Tim Chan, Simon C. Benjamin
Fault-tolerant quantum computers use decoders to monitor for errors and find a plausible correction. A decoder may provide a decoder confidence score (DCS) to gauge its success. We…

An Entanglement Monotone from the Contextual Fraction
Tim Chan, Andrei Constantin
The contextual fraction introduced by Abramsky and Brandenburger defines a quantitative measure of contextuality associated with empirical models, i.e. tables of probabilities of m…
